Resources developed by in-house experts.

Unlike other online learning companies, K¹² has made an unusual commitment to develop a number of learning resources in-house, with our own staff of subject matter experts. We did this for one basic reason: What existed did not fully measure up to our standards.

We make available to you some of our individual, award-winning textbooks and our unique reading kit for early learners known as K¹² PhonicsWorks™. You may purchase any of these at our online store.

History Texts

K¹²'s The Human Odyssey series puts the story back in history with a gripping narrative of adventure, struggle, and triumph, helping us understand where we have been, where we are now, and where we might be headed.

The first volume begins the odyssey by exploring the development of civilization across a twelve-thousand year span, from the Ice Age to the Middle Ages, from cave paintings to stained glass windows, from crude huts to Gothic cathedrals. Beautifully illustrated with images, diagrams, maps, and charts in full color. Full glossary, pronunciation guide, and index. (7th Grade)

The odyssey continues in 1400 with the rediscovery of classical Greece and Rome during the Renaissance, and moves through major developments in Islamic and Asian cultures into the great Age of Exploration. The final half of the volume surveys the democratic and industrial revolutions that would see the birth of new nations and new ways of life, leading to the brink of World War I. Full-color images, diagrams, maps, and charts throughout. An appendix of geographic terms and concepts augments an atlas, glossary, pronunciation guide, and index. (8th Grade)

The complex 19th century political landscapes of Asia and Europe set the stage for the dramatic third episode in the odyssey, in which the Great War and the Russian Revolution give way to churning century of even greater war, uncertainty, and economic turmoil. Science heats up as the Cold War freezes international relations; and major new political hot spots develop even as humanity reaches out into space. The digital information revolution changes the very way we conceive the human odyssey at the gateway to the 21st century. Full-color images, diagrams, maps, and charts throughout. An appendix of geographic terms and concepts, atlas, glossary, pronunciation guide, and index are included. (High School)
